Despite many years of work by the
USGS, the British Geological Survey, the
Geological Survey of Canada, and many other
institutions on the standardisation of rock
nomenclature, there is still no
on the subject.
purposes of comparing mineral deposits, deposit
models, and exploration targets, it is necessary
to use constant terminology. The
BGS Rock Classification Scheme was chosen
for use in MineMatch because it is currently the
most comprehensively documented classification
system available in the world.
the geological description of the environment
from which each sample in this study was taken
is determined from the geological map, rock
types in the map legend had to be translated
into BGS Rock Classification System terms.
Rock type names for translation were taken from
the RXTYPE field of the digital geological map
of the Yukon. Since the RXTYPE field can
include more than one rock type (eg:
individual rock names were parsed out of the
field, and only then translated.
A list of all
the rock names parsed out of the RXTYPE field,
together with the BGS Rock Classification Scheme
names to which they were translated for use in
this study can be viewed by clicking on the
